Fimbristylis fimbristyloides (F. Muell.) Druce (Cyperaceae) belonging to Fimbristylis sect. Fuscae Ohwi, which has been ambiguous in terms of its distribution and taxonomic substance in Korea, was found on Amtae-do Island, Sinan-gun, Jeollanam-do in Korea. F. fimbristyloides is a small species that is approximately 5-15 cm tall and differs greatly from most taxa in that the spikelets are laterally compressed. In particular, F. fimbristyloides is similar to F. ovata but is distinguished by the height of the plants, falcated leaves, the number and size of spikelets per inflorescence, glabrous styles, the size of the achenes, and the presence of achene stalks. A description, differences from related species, a key to the taxa and photographs of Korean F. fimbristyloides are provided in this paper.
